Intelligent AB Turnstile Gate

The pedestrian turnstile AB gate system (also known as a dual-gate interlocking turnstile system) is an advanced access control device designed for high-security scenarios. It consists of two independently operated turnstiles (Gate A and Gate B) that are interconnected through an intelligent control system. Widely used in airports, customs, prisons, data centers, high-end office buildings, and other high-security venues, this system employs a "dual-gate interlocking" mechanism to effectively prevent tailgating, unauthorized entry, and other security breaches while ensuring efficient passenger flow.

1. Dual-Gate Interlocking Mechanism

• Function Description: Gate A and Gate B operate in a "one-open, one-closed" state, meaning Gate B remains closed when Gate A is open. Only after a person passes through Gate A and completes identity verification can Gate B open.
• Security Benefits:

    Prevents unauthorized individuals from tailgating, ensuring only one person passes at a time.

    Eliminates security vulnerabilities caused by single-gate malfunctions or deliberate breaches.

2.Anti-Tailgating and Anti-Pinch Features

• Infrared Sensing + Pressure Detection:

    Multiple infrared sensors monitor the number of individuals in the passage in real time. If unauthorized entry is detected, the system            triggers an alarm and locks the gates.

    If resistance is encountered during gate closure (e.g., pinching), the gate immediately stops and reverses to ensure safety.

• Audible and Visual Alarms:

    Alerts are triggered for unauthorized entry, reverse passage, and other abnormal behaviors, with visual indicators highlighting the issue.

3.Emergency and Special Scenario Handling

• Power Failure Unlocking:

    In case of sudden power outages, gates automatically unlock and remain open to ensure safe evacuation.

• Manual/Remote Control:

    Administrators can manually open gates via control panels or remote terminals during emergencies.

• Fire Alarm Integration:

    Automatically opens gates upon receiving fire alarm signals.

• High Security: Dual-gate interlocking and multi-layer verification eliminate unauthorized access.
• Efficient Passage: Rapid identity verification and intelligent sensing reduce waiting times.
• Flexible Deployment: Modular design adapts to various sites and requirements.

• Government Institutions: Administrative halls, archives, and other sensitive areas.
• Transportation Hubs: Airport and high-speed railway security checkpoints.
• Industrial Parks: High-security enterprises or laboratories.
• Public Facilities: Museums, libraries, and other venues requiring crowd control.
